Geographic Distribution of Fruit Color
Fruit Color Where Species Having A Certain Fruit Color Grow Clade in Miller et al. 2011

In the figures above:

The orange fruits are from collection Mione 707, not yet named (photo by Thomas Mione).
The black fruits are those of J. repandidentata grown in Connecticut (photo by Thomas Mione).
The green fruits are from J. chihuahuensis, scanned from a slide generously provided by Robert Bye (photo by Robert Bye)
The red fruits are from J. auriculata, grown in Connecticut from seed generously provided by R. Lester (BIRM S. 1596) and passed on to T. M. by Dick Olmstead, grown as Mione 450, original collection Plowman 4449 (photo by Thomas Mione).

Figure 5. Fruit diversity within the Jaltomata procumbens complex. Accession 321 is distinct enough to have been given its own webpage (link to 321). Smallest units are mm. Photo by CCSU student Emmett P. Varricchio at the University of Connecticut greenhouse.
Figure 6. Wet mount of outermost part of fruit of Jaltomata procumbens; the purple pigment is almost certainly anthocyanin given that it occupies nearly all of the volume of the cell. No stain(s) were used. Slide made and photo by CCSU student Melissa R. Luna in the lab of Thomas Mione, December 2012, Mione 599.

 

In Mexico there are green-fruited morphs of two otherwise black/purple fruited species, J. procumbens (Cavanilles) J. L. Gentry (Williams, 1985), and J. chihuahuensis (Bitter) Mione & Bye (Mione & Bye, 1996).
